Description

Изобретение относитс  к композици м дл  защиты арматуры строительных конструкций от коррозии.This invention relates to compositions for protecting reinforcement of building structures from corrosion.

При использовании известных битумноцементных антикоррозионных покрытий, особенно в услови х повышенной влажности , снижаетс  сцепление арматуры со строительным материалом примерно на 30%.When using known bitumen-cement anticorrosive coatings, especially under conditions of high humidity, the adhesion of reinforcement to building material is reduced by approximately 30%.

С целью повышени  сцеплени  арматуры со строительным материалом и заш,итных свойств покрытий на основе битумов с минеральным наполнителем, предлагаетс  вводить в состав указанных композиций негашеную известь в количестве от 5 до 15% от веса минерального наполнител .In order to increase the adherence of the reinforcement with the building material and the protective properties of coatings based on bitumens with mineral filler, it is proposed to add quicklime in the amount of 5 to 15% by weight of the mineral filler to the composition of these compositions.

Пример. 1 вес. ч. битума с повышенной температурой разм гчени  смешивают с 2,5 вес. ч. молотого песка (90%) и негашеной извести (10%). Песок примен ют с удельной поверхностью 900-1200 см/г, активность смеси составл ет 13-18%. Смесь нагревают до 140-150°С дл  возможности погружени  в нее. арматуры, длительность выдержки которой в гор чей смеси зависит от температуры самой арматуры и от желаемой толш,ины покрыти  и колеблетс  в пределах нескольких минут (чем длительнее выдержка, тем тоньше получаемое покрытие ). Затем арматуру вынимают, покрытию дают затвердеть в течение нескольких минут, после чего арматура готова к укладке в формы. При дальнейшей автоклавной обработке строительной детали арматурное покрытие прочно сцепл етс  с арматурой и строительным материалом.Example. 1 weight. including bitumen with a high softening temperature is mixed with 2.5 weight. h. ground sand (90%) and quicklime (10%). The sand is applied with a specific surface of 900-1200 cm / g, the activity of the mixture is 13-18%. The mixture is heated to 140-150 ° C for immersion. rebar, the duration of exposure of which in the hot mixture depends on the temperature of the rebar itself and on the desired thickness, or the coverage varies within a few minutes (the longer the exposure, the thinner the resulting coating). Then the reinforcement is removed, the coating is allowed to harden for a few minutes, after which the reinforcement is ready for laying in the molds. With further autoclave treatment of the construction part, the reinforcement coating adheres firmly to the reinforcement and building material.

Нова  композици  имеет повышенные защитные свойства, легко наноситс  на арматуру , не требует специальной сушки и достаточно эластична дл  транспортировки арматурного каркаса.The new composition has increased protective properties, is easily applied to the reinforcement, does not require special drying, and is sufficiently elastic to transport the reinforcement cage.
